, 1 1 This invention relates to a novel self-selvaging attachment for looms which is detachably mounted on and supported by the temple and which operates effectively to make possible the weaving of cloth having a soft or looped selvage and without the use of a wire run through the harness, reed and temple and which causes considerable loom damage and frequent loom stop- .wire runthrough the selvage edge of cloth.

Still a further object of the invention is to provide a self-selvager having a yicldably mounted needle for engaging the filling loop at a selvage edge of the cloth, which is displaceable upwardly out of engagement with the loop by operation of the loom and which is normally retained yield ably in substantially an upright position but swingable toward an inclined position to enable the needle to more readily disengage the filling loop.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of] the drawings, illustrating a presently preferred embodiment thereof, and wherein:

8 Claims. (Cl. 139195) the purpose of illustrating the application and use of the s 'elf-selvager, designated generally I and comprising the invention, a portion of the right-hand side of a conventional loom, designated generally 3 has been illustrated in the drawings, includinga portion of the right-hand temple 9, the lay beam. l0, reed cap H and'reed 12, illustrated in Figures 1 and 2. The loom harness i3 is also illustrated in Figure 1 and the loom shuttle M is shown in Figure 2. The loom parts 9 to M are all of conventional construction and have been illustrated and briefly described merely because these parts function with the self-selvager, designated generally 1.

The self-selvager 1 includes an elongated channel shaped housing I5 having a bottom l6 and corresponding upstanding substantially parallel side walls I? and E8. The housing bottom 16 is secured by fastenings I!) to the top of the temple 9. The side walls I! and I8 are provided with corresponding aligned longitudinally extending slots or openings 20.

An actuator, designated generally 2| includes a head portion 22 which is loosely disposed'in the housing I5 and which is provided adjacent its rear end withlaterally projecting noncircular lugs 23 which extend outwardly through and slidably engage the slots and which nonturnably fit therein to support the head 22 above and substantially parallel to the housing bottom [6. The head 22 is provided with a relatively deep and wide notch 24 at its forward end. A pin 25 extends transversely through the forward part of the head 22, transversely through the notch '24 and has its ends slidably engaging the 'slots 20 to cooperate with the lugs 23 to prevent rocking movement of the head 22 in the housing 15. The pin 25 is rotatably and detachably mounted in the notched forward end of the head 22. The actuator 2l,includes a shank 26 of re- 'stricted width which extends rearwardly from the head 22 and downwardly behind the housing 15 and temple 9. The shank 26 terminates at its lower end in a forwardly projecting lay beam engaging portion 21 which is normallydisposed forwardly of the lay beam stop 9a of the temple 9, as illustrated in Figure 2. A rod 28 extends across the upper portion of the housing IS, intermediate of its ends, and the ends of said rod are anchored in the upper portion of the walls I! and .18., An 'apertured ear 29 projects up wardly from the upper portion of the shank 26. A pull spring '30 has one end connected to the ear 29 and its opposite end anchored to the rod 28 for normally urging the actuator -2| forwardly elongated construction,'has a vertically enlarged rear end 32 which fits loosely in the notch 24 and has a central opening 33 therein through which the pin 25 extends. A setscrew 34 is threaded into the carrier portion 32 and is adapted to bev advanced into the bore 33 and into engagement with the pin 25 for securing the rear end 32 of the carrier to said pin 25 and to additionally retain the pin in engagement with the forward end of the actuator head 22 and in engagement with the slots 2|]. The upper portion of the forward end of the needle carrier 3| is provided with an upwardly and forwardly projecting bifurcated or notched extension 35 which is disposed forwardly of the remainder of said carrier 3| and through which a needle supporting pin 35 extends. The needle supportingpin 35 is journalled in the extension 35 and extends through the notch 37 thereof. A filling loop engaging needle 38 has an upper end extending through the notch 31' and through a diametrical opening 38 of the pin 36, which is likewise disposed in the portion of the pin 36 located in said notch 33.. A setscrew 40, which is disposed in the notch 31, is threaded radially into the pin 36 and is advanced into engagement with the needle 38 to clamp the needle in the bore 33. The lower portion of the notched extension 35 is provided with a bottom needle stop 4| and the upper portion of said ex;- tension 35 has an upper needle stop :32. The needle stops 4| and 42 extend transversely across the inner portion of the notch 37. One end of the needle supporting pin 35 projects outwardly from one side of the extension 35 and has 2. diametrical bore A3 extending therethrough, at an angle to the bore 33 in which one straight end of a spring 44 is disposed. The spring 44 has an angularly turned opposite end 45 which is anchored in a transverse opening 46 of the needle carrier 3|. The spring 44 is coiled as seen at 41 intermediate of its ends and acts to resist movement of the first mentioned spring end from its position as illustrated in Figure 6, in which position the pin 35 is held against rotation and in a position so that the needle 38 will abut the lower stop 4|.

The needle carrier 3| has a downwardly and forwardly inclined bottom edge 48 forming a cam surface for engagement with the forward edge 49 of the housing bottom I6. The forward end of the cam surface .48 extends to the forwardlend of the lower portion of the carrier 3| and which is disposed substantially behind or rearwardly of the extension 35. The rear portion 32: of the carrier 3| isprovided with a depending projection or detent 50 which is adapted to engage an upstanding projection of the housing bottom I forming a stop 5|, when the actuator 2| and needle carrier 3| are in forwardmost, operative positions.

It is to be understood that a corresponding selvager attachment 1 is mounted on the lefthand loom temple, not shown, the selvager attachment I as illustrated being disposed over the right-hand selvage edge 52 of a piece of cloth being woven on the loom 8, partially illustrated by the warp 53 and by the weft or filler 54. The other, left-hand selvager, not shown, associated th e han temp -9. ne sh n u he mounted v r. he other, eft-ha dsel e ed e not shown, of the cloth. Assuming the loom parts and the selvager attachment parts to be in the positions as illustrated in Figure 1, as the lay beam l0, reed cap I and reed l2 move rearwardly of the loom or from left to right of their positions of Figure 1, the lay beam ill will move away from the stop 9a and toward its position of Figure 2. When this occurs, the lay beam |0 moves out of engagement with the lay beam engaging portion 2l=of the'actuato'r 2| allowing the spring 33 to displace the actuator 2| and carrier 3| forwardly of the housing l5 from their positions of Figure 1. In the forward movement of theseparts, the lugs 23 and pin 25 slide forwardly of the housing l5 in the slots 23. The cam surface. lfimoves forwardly relatively to the forward edge 49 of the bottom it and if the carrier 3! does not swing downwardly by rotation of the pin 25 in the slots 2c due to its weight, the detent 50 will strike the stop 5| and cause the carrier 3| to swing downwardly or clockwise, as seen in Figures 2 and 4 to its operative position and with the needle 33 disposed in Substantially a vertical position against the lower stop 4|. The needle 38 will assume a position outwardly of the right-v hand selvage edge 52, as illustrated in Figures, 2 and 4. This occurs while the lay beam I3, reed cap Ii and reed l2 are moving toward the back of the loom or from the forward position of these parts as illustrated in Figure 1 in a direction to the right to the rearmost position of these parts as illustrated in Figure 2. With the parts thus disposed, the shuttle I4 carrying the filling 54 moves from the right'side of the loom, as illustrated in Figures 1 and 2, to the left or far side thereof, between the reed and temple 3. The shuttle Mforms a selvage loop 55 in a conventional manner at the right-hand selvage edge 52 around the lower portion of the needle 38. Thereafter, the lay beam {0, reed cap ii and reed |2 move toward the front of the loom or to theleft from their positions of Figure 2 to their positions of Figure 1, so that the filling will be packed by the reed in a conventional manner During this movement, the newly formed selvage loop 55 is held by the needle 38 until the reed i2 approaches the. filling 54, at which time the forward end of. the lay beam l3 strikes the actuator portion 2! and moves it from its position of Figure ,2 to its position of Figure 1. The actuator 2| being thus moved exerts a pull on the carrier 3i as the actuator is moved in the housing l5 from its advanced positioneof Figure 2 to its retracted position of Figure 1. As the carrier 3| moves toward a retracted position, as illustrated in Figure 1, its cam surface 48 by engagement with the housing edge 49 causes the carrier 3| to swing with the pin 25 in a counterclockwise direction in the housing l5 for rocking the carrier upwardly as it is moved to the left from its position of Figure 2 to its position of Figure 1. This upward swinging movement of the carrier 3| causes the needle 38 to be withdrawn upwardly out of the loop 55. In order that the needle 38 will not bind in the loop 55, since it is moving to the left as it is drawn upwardly, the needle 38 is swingably supported by thepin 35 which per- 'mits the needle to swing counterclockwise by a 42. The needle bears against the lower stop il in its normal vertical position. The movement of the carrier 21 to the left will also load the spring 33 so that when the lay beam it again moves to the right from its position of Figure l, as previously described, the spring 36 will return the actuator 22! and carrier 3| to the operative positions of these parts as illustrated in Figures 2 and 4, and as previously described.

Various modifications and changes are con.- templated and may obviously be resorted to, without departing: from the spirit or scope of the invention as hereinafter defined by the appended claims.
